Bugs

  1. Cannot access the second element in a vector column (07 Mar 2008)

    dmkeypar cannot be used to get information from the second element in a vector column, e.g. the second R value from a wavdetect source file:

    unix% dmlist s3_src.fits"[cols R][#row=1]" data
    --------------------------------------------------------
    Data for Table Block SRCLIST
    --------------------------------------------------------
    
    ROW    R[2]
    
         1 [        3.8186242580         2.8336687088]
    
  2. If a filter yields zero rows, the tool returns bad data. (18 May 2010)

    Run twice in a row, the following command returns different, incorrect values. This is due to the fact that there are only 142 rows, so a filter on row number 999 is empty:

    unix% dmkeypar file.fits"[#row=999]" col_mod echo+
    6104498
    
    unix% dmkeypar file.fits"[#row=999]" col_mod echo+
    3552690
    
    unix% dmlist file.fits counts
    142
